This book is about the processing, microstructure and properties of materials in fibrous form. This is the first book to cover the whole range of fibers, spanning natural polymeric fibers such as silk, synthetic polymeric fibers such as aramid and polyethylene, metallic fibers such as steel and tungsten, and ceramic fibers such as alumina and silicon carbide. The text contains large numbers of diagrams and micrographs to bring home to the reader the important principles and concepts. It will be of value to workers in the fields of materials science and engineering, metallurgy, ceramics, textile physics and engineering, mechanical engineering and chemical engineering.
